Aston Villa boss Paul Lambert says striker Darren Bent is not for sale ahead of the close of the transfer window.
It is understood Saphir Taider is set to leave Southampton just three weeks after arriving on a season-long loan.
Bolton have completed the loan signing of Norwich midfielder Jacob Butterfield.
The 22-year-old will spend a month at the Reebok Stadium and is Dougie Freedman's first signing as Wanderers manager.
Butterfield damaged his anterior cruciate ligament while playing for Barnsley against Leeds last New Year's Eve and moved to Norwich this summer despite his ongoing recovery from surgery.
The England Under-21 international has made two appearances for the Canaries this term, both in the Capital One Cup victories over Doncaster and Tottenham.
He is available to make his Bolton debut in the npower Championship trip to Blackpool this weekend.
